Replacing CDR220+DSP (M680)

Recommended Posts

I have a 00S with DSP option, everything is stock. I am considering replacing the head unit with a Double DIN Pioneer X920BT. Looking for advise on the following questions:

1) Does it mean that I would have to replace the DSP amp as well?

2) Should the door speakers be wired as subwoofer? The highest crossover frequency allowed by the Pioneer is 125Hz. If not wire as sub, would it be a copy of front channel?

3) Since 6-channel amp are hard to come by in appropriate size, I am considering running a 4-channel for dash and door, and running the rear channel directly off the head unit internal amp. I have not found any spec on the rear speaker to verify if that would be OK.

I am thinking about doing the same thing. I have a 97 Boxster and am looking to replace the factory stereo with a double din unit. The Pioneer AVIC-X910BT gets excellent reviews and would add GPS and hands-free bluetooth to my Boxster. I found a good review of the head unit here:


I found a good sale on the head unit here:


Anyway I wanted to know if there was anyone else that had replaced the factory stereo with a double din unit, what parts would be used, and how difficult it was. Any additional info would be great especially if anyone has found an upgrade kit for the dash.

Yes, I understand double DIN installation info is plenty full. My question was whether a double DIN install could coexist with DSP amp option (i.e. without replacing the DSP AMP). One of the challenge would be to have both the AC panel and the DSP panel on the lower center console. I'm not sure whether that is feasible since my own measurement seem to indicate it's not. Appreciate any suggestion or advice.

Here is a link for information on installing a 2DIN navigation system in Boxsters up through MY 02 (pre-MOST bus):

Here is a link to a source for the hardwear needed for the installation:
